A pre-amp is essential equipment in any audio studio (yes even before your USB microphone!). This is the magic device that is used to boost all types of audio signals such that they can be recorded onto a recording device. A good quality pre-amp is necessary to make sure that good quality audio signals are recorded. This is the reason why even if you have a top class microphone you cannot hope to have perfect recording quality unless you have proper pre-amp. Though the vice versa also holds true you need to check for the quality of your pre-amp if you have problem recording sound.
In most cases, most mixers come with internally built pre-amps. But most of the time professionals might want to utilize external pre-amp for better results. It is possible to decide whether or not you require an external pre-amp by checking your recorded sound quality; if the recorded sounds are good then you can forgo the external pre-amp. If not then you might want to purchase a good and quality one for quality recording. Investigating the different types of pre-amp can be an essential factor in case you want to select the best model suitable for your needs.

Though all the about types are available for various purposes, it is essential to understand which type suits your needs the best. Though all types of pre-amps are quite popular, most people prefer the solid state pre-amps. The main reason for this is that this type of pre-amps uses transistors to boost sound levels. Hence depending on your requirement you can either get crystal clear voice or you can opt for distortion for the twist in the audio required.
